Lawmakers had to pause for a fact check about a 78-year-old law during a hearing that was supposed to be about ObamaCare, after Rep. Charles Rangel made the -- inaccurate -- claim that no Republicans supported the Social Security Act.

The New York Democrat made the assertion Tuesday while railing against Republicans for opposing the health care law. It was during a House hearing where Marilyn Tavenner, head of the Centers for Medicare & Medicaid Services, was testifying.

"It should give you some small comfort to know that, historically, the Republican Party always fought vigorously against these types of programs," Rangel said. "I don't think that one Republican voted for the Social Security Act."
